Hi,

I have linked theora and ogg libs into an OpenGL game engine. I have
successfully decoded a frame to the YUV buffer, and then converted that to
RGB. I really want to use alpha channels in the ogg movies. Does the
yuv_buffer structure support alpha channels? Any advice on how to get an
RGBA buffer would be greatly appreciated. 

Thanks,

Lee
